Competition between endogenous and exogenous orienting of visual attention   总被引:5,自引:0,他引:5  
The relation between reflexive and voluntary orienting of visual attention was investigated with 4 experiments: a simple detection task, a localization task, a saccade toward the target task, and a target identification task in which discrimination difficulty was manipulated. Endogenous and exogenous orienting cues were presented in each trial and their validity was manipulated orthogonally to examine whether attention mechanisms are mediated by separate systems and whether they have additive and independent effects on visual detection and discrimination. The results showed that each orienting mechanism developed its typical and independent effect in every case except for the difficult identification task. A theoretical framework for understanding the relationship between endogenous and exogenous orienting of attention is proposed, tested, and confirmed.  相似文献

Systematic client feedback (SCF) is increasingly employed in mental health services worldwide. While research supports its efficacy over treatment as usual, clinicians, especially those who highly value relational practices, may be concerned that routine data collection detracts from clinical process. This article describes one SCF system, the Partners for Change Outcome Management System (PCOMS), along a normative (standardized measurement) to communicative (conversational) continuum, highlighting PCOMS’ origins in everyday clinical practice. The authors contend that PCOMS represents “both/and,” providing a valid signal of client progress while facilitating communicative process particularly prized by family therapists steeped in relational traditions. The article discusses application of PCOMS in systemic practice and describes how it actualizes time‐honored family therapy approaches. The importance of giving voice to individualized client experience is emphasized.  相似文献

This study investigated the reciprocal relationship between perceptions of psychological contract fulfilment and employee performance (sales made and sales targets), and whether this was moderated by the quality and length of the social exchange relationship captured, respectively, through perceived organizational support (POS) and organizational tenure. We used a sample of 146 sales advisors and a four‐point longitudinal design and found support for reciprocal links where performance predicted subsequent psychological contract fulfilment and vice versa. The strength of the relationship between performance and psychological contract fulfilment increased over time. The quality of the social exchange relationship (i.e., POS) moderated reciprocal links between sales made and sales targets met and perceptions of psychological contract fulfilment at earlier, but not later, time points. One way to interpret the findings is the changing nature of the unfolding relationship between support, psychological contract fulfilment, and performance, where a supportive relationship buffers failing to deliver at earlier time points, but at later time points employee performance and psychological contract fulfilment associate more strongly as both parties prioritize delivery.  相似文献

Understanding the perception of multiracial persons is increasingly important in today's diverse society. The present research investigated the process of categorizing multiracial persons as “Multiracial.” We hypothesized that perceivers would make fewer Multiracial categorizations of multiracials and that these categorizations would take longer than monoracial categorizations. We found support for these hypotheses across six experiments. Experiment 1 demonstrated that perceivers did not categorize morphed Black–White faces as Multiracial with the same frequency with which they categorized Black and White faces as Black and White (respectively), and that categorizations of multiracials as Multiracial took longer than monoracial categorizations. Experiment 2 replicated and extended these effects to real Black–White faces. Experiment 3 showed that these findings generalized to Asian–White faces. We used pixel variance analysis to show that these effects were not due to increased variance among Multiracial faces. The image analysis showed that the Black–White morphs and real biracials were actually less varied than either the Black or White sets of faces. Experiments 4 and 5 demonstrated that cognitive load and time constraints detrimentally affected multiracial, but not monoracial, categorizations. Experiment 6 showed that imbuing monoracial categories with importance decreases the use of the Multiracial category. Implications of these findings for understanding perceptions of multiracial persons are discussed.  相似文献

This paper describes and discusses the ancient superstition of the Evil Eye. The author describes his own personal childhood introduction to the subject of the Evil Eye which years later instigated his scholarly inquiry. The history of this very geographically widespread folk belief is elaborated upon, along with common manifestations as they appear in a number of different countries and cultures. Some of the methods used to thwart the negative effects of the Evil Eye are enumerated. Relevant psychodynamics and common expressions of the Evil Eye superstition are elucidated upon.  相似文献

The coincidence of historical trends in youth antisocial behavior and change in family demographics has led to speculation of a causal link, possibly mediated by declining quality of parenting and parent–child relationships. No study to date has directly assessed whether and how parenting and parent–child relationships have changed. Two national samples of English adolescents aged 16–17 years in 1986 (N = 4,524 adolescents, 7,120 parents) and 2006 (N = 716 adolescents, 734 parents) were compared using identical questionnaire assessments. Youth-reported parental monitoring, expectations, and parent–child quality time increased between 1986 and 2006. Ratings of parental interest did not change. Parenting differences between affluent and disadvantaged families narrowed over time. There was thus little evidence of a decline in quality of parenting for the population as a whole or for disadvantaged subgroups. Parent-reported youth conduct problems showed a modest increase between 1986 and 2006. Findings suggested that the increase in youth conduct problems was largely unrelated to observed change in parent–child relationships.  相似文献
